Advanced technical ceramics - Methods of test for ceramic coatings - Part 6: Determination of the abrasion resistance of coatings by a micro-abrasion wear test
This part of EN 1071 specifies a method for measuring the abrasive wear rate of ceramic coatings by means of a micro-scale abrasion wear test, based on the well known crater grinding technique used for film thickness determination (see EN 1071-2).
This method can provide data on both film and substrate wear rates, either by performing two separate tests or by careful analysis of data from a single test series.
The test method can be applied to samples with planar or non-planar surfaces but the analysis described in clause 9 applies only to flat samples. For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
Hochleistungskeramik - Verfahren zur Prüfung keramischer Schichten - Teil 6: Bestimmung der Beständigkeit gegen Abriebverschleiß von Schichten mittels Mikroabriebprüfung
Dieser Teil von EN 1071 legt ein Verfahren zur Messung der Abriebverschleißrate keramischer Schichten durch eine Mikroabriebprüfung fest, die auf dem von der Bestimmung der Schichtdicke bekannten Kalottenschleifverfahren basiert (siehe EN 1071 2).
Nach diesem Verfahren können Daten zur Bestimmung der Abriebverschleißraten sowohl der Schicht als auch des Grundwerkstoffs ermittelt werden, indem entweder eine Prüfung für die Schicht und eine Prüfung für den Grundwerkstoff oder aber eine Analyse durchgeführt wird, bei der eine sorgfältige Auswertung der aus nur einer einzigen Prüfserie gewonnenen Daten erfolgt.
Das Prüfverfahren kann auf Proben mit ebenen oder nicht ebenen Flächen angewendet werden, während die im Abschnitt 9 beschriebene Analyse nur auf flache Proben anwendbar ist. Für nicht ebene Proben ist eine komplexere Analyse erforderlich, möglicherweise unter Anwendung numerischer Verfahren.

EN ISO 17025, General requirements for the competence of testing and calibration laboratories (ISO/IEC 17025:2005) ISO 3290, Rolling bearings — Balls — Dimensions and tolerances 3 Terms and definitions For the purposes of this European Standard, the following term and definition applies. 3.1 abrasive wear rate, K abrasive wear coefficient volume of material removed in unit sliding distance under a normal contact load of 1 N 4 Significance and use Although few protective coatings are subject to single wear processes, the abrasive wear resistance of such coatings can play a decisive role in their performance. Hence knowledge of the abrasive wear resistance of ceramic coatings can help in the proper selection of coatings for applications where abrasion plays a major role in their degradation. Although techniques exist to measure the abrasive wear behaviour of bulk materials and thick films (see [1 – 3]), these techniques are not easily applied to thin films and are difficult to interpret when used on curved surfaces.
The purpose of this European Standard is to provide a method for measuring the abrasion resistance of both thin and thick coatings and of bulk materials. The test can be performed on flat surfaces or surfaces with a known radius of curvature, and requires only a few mm2 of sample. However, the analysis described in clause 9 applies only to flat samples, and is applicable to homogeneous single layer coatings only; errors may occur if the test is used on in-homogeneous coatings. [4] and [5] give details of analytical treatments for determining the wear rate for coatings on curved surfaces.
By proper treatment of the results, as indicated in 9.2, where the test produces penetration of the coating it can provide abrasive wear coefficients for both the coating and substrate from a single test series.

The recommended conditioning treatment consists of running the new test ball for at least 300 revolutions on a non-critical part of the sample, or other suitable surface, under normal test conditions and repeating this for at least 5 different orientations of the ball before starting the test programme. NOTE 2 A flat, ground steel coupon with a hardness of between 200 and 800 HV 30 has been found to be suitable for conditioning the ball. NOTE 3 Following conditioning, balls have been found to be usable for around 50 individual craters, depending on the precise conditions used.
The performance of balls shall be subject to regular performance checks to ensure that they continue to produce a
